Use case: user DnD DB table onto GUI form in order to display DB data in this
When the user drags the table we have to be able to find out whether there (=in
the project) is an entity class that corresponds to the DB table. If there is
not such a class, we will generate it. We need to be able to find a persistence
unit for the given DB connection (e.g. given DB url, driver, username and
password) to be able to find out whether the entity class exists and if not, to
be able to add the generated class into the right persistence unit.
By now, we are able to find the existing persistence unit using
ProviderUtil.getProvider(pUnit), Provider.*, ProviderUtil.getProperty(pUnit,
propertyName) methods. If these methods are going to survive in NB 6.0, it is
sufficient to add us (org.netbeans.modules.form.j2ee) as friends to
I see that the relevant methods in ProviderUtil still exist in the trunk
codebase, and Matisse is a friend of the persistence module. So if there are no
changes planned for 6.0, then we are done, right?
Are we done then?
From my point of view, though the methods still exist, I'd keep this open until
the j2ee/persistence friend API has been cleaned up a bit (similarly to issue
96777). There might be a need for some minor changes in some of the
I cleaned up the ProviderUtil class a bit and added / improved JavaDocs. The
methods you need for this are still there and you've been added as a friend, so
I'm closing this now.
